Blender 2.65 .blend file is not loading correctly in Blender 2.76b
That's to be expected. Blender 2.7 has broken some backwards compatibility (which is part of the reason why it took so long to be released).


  For 2.7x projects we will allow forward and (minor) backward compatibility breakage. That means that by default, the 2.7x .blend files don”t have to read reliably in 2.6x or older. Backward compatibility stays crucial though, and should only be acceptable for big and important improvements.


From the Blender Roadmap for version 2.7.

If it is essential to be able to open this file, I recommend using version 2.69.
